About reporting....For example, I want to create new report which display not only deployment model of my servers in Enterprise Architecture but total number of cores, RAM HDD/SDD, cost of each server etc. per each Information System in one list (as I see I can use Properties attribute for that and then sum up it for each server).

As I thought I can do customization in Jasper Studio but I can not establish right path to the Archi jar file.

If you say that I should use Archi for reporting then my question is - how to implement this type of customization using Archi ?

I'm afraid I'm not going to be much help regarding Jasper Reports. When I initially created the Jasper Reports for Archi I wrote each jrxml file by hand and tested them from Archi using a long process of trial and error. It was not the best way to do it, for sure!

It seems you've not fully read what I shared: you can (and should) use Jasper Studio to edit your report files. You don't have to configure any path to Archi jar files. You simply have to edit your report files in Jaspter Studio and then use them like any other custom report from within Archi.

My report should make total report for all 5 servers where the fields should be:cores - should be calculated and be equal 41 coresRAM - should be calculated and be equal 20 GbCost - should be calculated and be equal $35 200

How to achieve it in Archi or Jasper ?

I need it because those servers is One IT system. Those propeties are used to control and manage Enterprise Architecture (updates, changes, new development, how much it cost, what happend if business will change their strategic goals and how it will influence on that One IT system).

By edit I mean doing everything,including creating your own report from scratch.

BTW, if you only want to extract information, you can also execute some SQL query using the HTML export (which contains a "query" tab in the main windows, the one you have by default and when you clic on the model name).
